Connecting a QFX3600-I Interconnect Device to a Copper-Based QFX3000-M QFabric System Control Plane Network

Before you begin to connect a QFX3600-I Interconnect device to the copper-based QFX3000-M QFabric system control plane and management network:

  • Install your QFabric system hardware (Director group, Interconnect devices, and Node devices). For more information, see Installing and Connecting a QFX3100 Director Device, Installing and Connecting a QFX3600 or QFX3600-I Device, and Installing and Connecting a QFX3500 Device.

    Note:

    There can be a maximum of four Interconnect devices in the QFX3000-M QFabric system.

  • Install your EX4200 switches. See Installing and Connecting an EX4200 Switch.

    Note:

    For a copper-based control plane network, use EX4200-24T switches with an SFP+ uplink module installed.

  • Interconnect the two EX4200 switches using the 1-Gigabit Ethernet SFP+ uplink module ports. See Interconnecting Two EX Series Switches for QFX3000-M QFabric System Control Plane Redundancy.

  • Ensure that you have two RJ-45 patch cables available for each Interconnect device. For cable specifications, see Cable Specifications for Copper-Based Control Plane Connections for the QFabric System.

  • Use Table 1 to determine the QFX3600-I Interconnect device-to-EX4200 switch port mappings. Specific ports have been reserved on the EX4200 switch to connect to each of the QFX Series device types. Such design simplifies installation and facilitates timely deployment of a QFabric system.

    Note:

    The numerical identifiers for each Interconnect device below are not preassigned to the Interconnect devices that are shipped to you. They represent the order in which you connect the Node devices. For example, the first Interconnect device (IC0) is connected to port 16 (ge-0/0/16) on the first EX4200 switch EX0 and the second EX4200 switch EX1.

A QFX3000-M QFabric system control plane and management network is formed by connecting the QFX Series devices in your network to two EX4200 switches. QFX3600-I Interconnect devices have two 1000BASE-T management ports (labeled C0 and C1) with RJ-45 connectors. For a copper-based control plane network, use the 1000BASE-T management ports to connect the QFX3600-I Interconnect device to each EX4200 switch (see Figure 1).

Specific ports have been reserved on the EX4200 switch to connect to the Interconnect devices, Node devices, and QFX3100 Director devices in your QFabric system. Such design simplifies installation and facilitates timely deployment of a QFabric system.

To connect each QFX3600-I Interconnect device to the copper-based control plane network:

  1. Connect the first QFX3600-I Interconnect device.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
    2. Connect the other end of that cable to port ge-0/0/16 on the first EX4200 switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/16 on the second EX4200 switch.
  2. Connect the second QFX3600-I Interconnect device.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
    2. Connect the other end of that cable to port ge-0/0/17 on the first EX4200 switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/17 on the second EX4200 switch.
  3. Connect the third QFX3600-I Interconnect device if used.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
    2. Connect the other end of that cable to port ge-0/0/18 on the first EX4200 switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/18 on the second EX4200 switch.
  4. Connect the fourth QFX3600-I Interconnect device if used.
    1. Connect one end of the first RJ-45 patch cable to the management port labeled C0.
    2. Connect the other end of that cable to port ge-0/0/19 on the first EX4200 switch.
    3. Connect one end of the second RJ-45 patch cable to the management port labeled C1.
    4. Connect the other end of that cable to port ge-0/0/19 on the second EX4200 switch.
